Full floating type electrothermal warming immersion suit

Abstract

The invention belongs to the technical field of marine lifesaving equipment, and relates to a full floating type electrothermal warming immersion suit. A water-immersed immersion suit is used as a carrier, a graphene-magnesium seawater battery is used for power supply, and a graphene flexible electrothermal film is used as an electrothermal element. The battery is immersed in water for 1-2 min, and a hydrosol film is automatically detached to activate the battery to supply power. The electrothermal film makes temperature between a human body and the immersion suit is 20-30 DEG C. A drowning person does not drop body temperature when floating and immersing in a lower temperature water area at 0-2 DEG C for 6-8 h. After 6-8 h, an insulation function of the DBF-II type water-immersed immersion suit plays a role. After the drowning person is immersed in the seawater for 6 more hours, the body temperature of the drowning person drops to lower than 2 DEG C, the immersion suit can realize heating and warming of a whole body to effectively supplement heat loss. The full floating type electrothermal warming immersion suit is simple in structure and convenient in operation, can cater to thegeneral public, does not affect the normal functions when stored in environment of 30 DEG C-60 DEG C, and is suitable for all types of ship and offshore operation platforms in various navigation areas.

Description

Technical field: [0001] The invention belongs to the technical field of marine lifesaving equipment, and in particular relates to a full-floating electric heating immersion suit, which is powered by a graphene-magnesium seawater battery, and a graphene flexible electrothermal film is used as an electric heating element, which can realize the whole body electric heating warmth of the immersion suit. Background technique: [0002] With the development of the marine transportation industry, as well as the development of marine scientific research and marine resources, it has become normal for ships and offshore operating platforms to sail and operate in low-temperature seas. Accidents of falling into water and freezing to death happen from time to time. According to the data, if a person stays in seawater at a water temperature of 5-15°C for 10-15 minutes, he or she will experience physiological disturbances and lose consciousness, leading to death. People can only survive for ...

Chinese patent 201510945840.X discloses a low-voltage electric heating warm-keeping life jacket. The chest and back waist of the single piece in the back skirt are respectively glued and inlaid with the first electric heating film and the second electric heating film, and the left side of the second electric heating film is glued with a wire For the thermostat, a third electric heating film is glued and inlaid on the left front chest of the left front jacket, a fourth electric heating film is glued and inlaid on the right front chest of the right front jacket, and an inflatable layer is placed on the inside of the thermal hat One side of the back of the head is glued and inlaid with a fifth electric heating film. There are built-in fastening belts at the waist, the neck of the thermal hat, and the cuffs of the left thermal sleeve and the right thermal sleeve. There are upper buttons and lower buttons on the back of the garment; it is a vest-style structure, which has a large heat loss. In relatively calm water, it has a certain warming effect on the upper body of the drowning person, and it cannot keep the whole body warm.
